Addition # 4 – Here is another Brilliant pear, I cut all of them a often, and I like this one in particular. It works well in about any material, it is a little more work than a couple of my others, but a lot less than a normal pear. This works in Topaz and Peridot. Cut this in R.I. 1.62 to 1.76 (89.7%) without changes.
